Operating data note
For storage, mounting and operation of lead-acid batteries, the relevant
DIN/VDE regulations or country-specific regulations (e.g. VDE 0510 Part
2/EN 50272-2) must be observed. You must ensure that the battery site
is sufficiently ventilated. Possible sources of ignition must be at least 50
cm away.

ambient temperature during storage
Along with the storage and operating temperature, other factors such as
the duration of the storage period and the charge status during storage
have a decisive influence on the possible useful life. Batteries should
therefore be stored as briefly as possible, always fully charged, and
within the temperature range 0 to +20 °C.
